Bug description:
[Impact]
On 6.14+ kernel, no audio input/output for cs42l43 and cs35l56
on Intel LNL of ThinkPad X9-14.
[Fix]
The v2.12 sof of cs32l43 conflicts with 6.14 kernel.
v2.12 works with 6.11 kernel;
v2.12.1 works with 6.14 kernel.
Update the firmware:
v2.12.x/sof-ipc4-tplg-v2.12.1/sof-lnl-cs42l43-l0-cs35l56-l3-2ch.tplg
to sync with kernel 6.14 to support the audio.
sof-bin commit:
f4bdbcf v2.12.x: Update v2.12.1 new/updated topology files
[Test]
Tested on Intel LNL:
1, hear the sound from
$ speaker-test -c 2
2, make sound and recorded, replay the file:
$ arecord -f cd test.wav
$ aplay test.wav
Hear the recording.
[Where problems could occur]
It may break cirrus audio support.
